ER-SW Programmable AC Power Source
ER-SW series Programmable AC Power Sources have the ability to simulate the AC voltage and frequency used in all countries. They are excellent instruments for R&D,design production testing/evaluation,and QAverification. In addition, the frequency range covers 500 Hz, making these products ideal for commercial and defense avionics applications.
The ER-SWseries delivers maximum rated power for any adjustable output voltage up to 300Vac (L-N) / 520Vac (L-L )for 3 phase units, and at any adjustable frequency between 40Hz to 500 Hz.
It integrates IGBT made by Mitsubishi, Siemens, and Infineon, and combines microprocessor and ARM &DSP control design together for quick response and higher reliability and parallel operation.
